"Quinteto del tren" is a piece of music from "Cachencho en la playa," referenced several posts back in this thread. The latter is a record album (on cassette, says Horacio Salinas) based on the "Cachencho" television program for children in Chile. Composer Luis Advis, also referenced earlier, composed the music for that cassette album. It appears that Advis also wrote the lyrics, as I cannot find credits for a different lyricist.

"Cachencho en la playa" is NOT an Inti-Illimani product. Inti-Illimani was in its infancy, just getting started, when the television show "Cachencho" was being watched in households of children in their native country. An important point here is the time and history period. This album had already been published, and at least one copy was collected by an Inti-Illimani member, when the band left in the 1970's on that fateful tour which found them in Rome, Italy when Allende was assassinated. Therefore, the television show, the album, and composer Luis Advis are all links to the Chile that no longer exists, from which Inti-Illimani was exiled for roughly fifteen years.

There is more. The adult actor who played the very childlike character of Cachencho was -- I think I have the name right -- Fernando Gallardo; he had a career of some variety, but it seems that the role of Cachencho made him a household face/name. Gallardo had a sister named Ligea, who became....the wife of Horacio Durán, who plays the Bolivian charango and was one of the co-founders, with Jorge Coulon and Max Berrú, of the band that became Inti-Illimani. White-haired Durán, a tall large-framed man who dwarfs the miniature-sized charango strapped to his chest, is also the musician who, many years in the past, courted the big sister of Horacio Salinas, and persistently invited Salinas -- still a teenager -- to bring his guitar and join his brand-new, no-name musical group. Which, of course, became Inti-Illimani.

There was just time, after Inti-Illimani was permitted to end its exile and return to its native country of Chile, for Horacio Durán and Ligea Gallardo Durán to enjoy Fernando Gallardo's presence in their lives for a little while, and for Horacio Salinas, now the band's musical director and a full-fledged composer in his own right, to have a happy reunion with aging composer Luis Advis. Just enough time, and then Advis died, followed by Fernando "Cachencho" Gallardo. Advis was old, and his death was natural. Gallardo was not so old, and was stricken with terminal illness and suffered a mournful ordeal on his deathbed. Mass media announcements of Gallardo's death, showed a color photograph of the wake: the wooden coffin, closed rather than open, high off the floor in what appears to be the family home. Next to the coffin, seated in chairs, two stricken mourners: the dead man's surviving sister Ligea, and her equally grief-wracked husband, Señor Durán.

Thus, "Quinteto del Tren," which reminds me of one of those lightning-fast ensemble finales in an "opera buffa" by Rossini, summons deep and conflicting emotions, joyful piece though it is, in the elder statesmen of Inti-Illimani Histórico, who faithfully recorded composer Luis Advis' exact arrangement on their album "Travesura." In fact, an interview for the Latin-American website emol.com, in their native Spanish, remarked on a live performance in which the piece was introduced to the audience by Horacio Durán himself, who choked up while speaking. Bandmate Salinas explained in the interview, "It's because his wife Ligea was Gallardo's sister, and also he (Durán) just became a grandfather, so this is an emotional moment for him."
